Marty Jopson examines the popular myths and theories surrounding fizzy drinks as part of his Test Centre series of films.

First off - Why do some fizzy drinks explode when you add mints to them?

Marty explains that it's a combination of a chemical reaction and the rough surface of the mints that creates tiny bubbles which are forced upwards out of the bottle.

Second: Does leaving a silver spoon in sparkling wine prevent it from losing its fizz?

Through comparisons with and without a spoon Marty disproves that it makes a difference. In fact, says Marty, it's the naturally occurring gases given off by the wine that make it last longer than you would expect.

And finally: Does tapping a drinks can prevent it from spraying?

Marty builds a can shaking device to answer the question. He finds that it makes very little difference at all - completely disproving the myth.

Still to come in the series: Thunder and lightning, and can opera singers smash glasses with their voices?

What do you think about Marty's tests? Will you still be tapping your cans and leaving a spoon in the bottle?

    After wathcing the fizz experiment using the cans of pop, I realised that the test is not completely fair.
    If you watch carfully when the cans are being shaken there is a mixture of Sprite and Pepsi cans,when the cans are being tapped and then opened they are all Pepsi cans.
    This makes the test unfair as they are not the same type of drink and were not the the cans we saw being shaken.
